4tronix have just announced the availability of a board that will allow you to use your Raspberry Pi’s spare GPIO pins when using a HAT. For a while, several boards, such as the SenseHAT, have hogged the entire GPIO when they’re just using a few pins. Now, you can get access to the rest of the pins. The board, called an ‘intercept’ costs just £3.75+VAT and shipping from the 4tronix website. It’s an ingenious solution to the problem.
